Stereoselective Synthesis of Arylglycine Derivatives via Palladium-Catalyzed alpha-Arylation of a Chiral Nickel(II) Glycinate

摘要

A practical and efficient stereoselective synthesis of arylglycine derivatives was realized via palladium-catalyzed alpha-arylation of a chiral nickel(II) glycinate complex with aryl bromides. The structurally diverse arylglycine products were obtained in excellent isolated yields and with good diastereoselectivity. A simple acidic hydrolysis furnished optically pure arylglycines in high yield, and the chiral ligand (S)-BPB could be efficiently recovered and reused.
